Subject: [PATCH 0/2] Fix kernel buffer overruns caused by bit flips
Date: Fri, 02 Feb 2018 18:23:41 +0100 [thread overview]
Message-ID: <1517592221.3137.18.camel@HansenPartnership.com> (raw)
If a TPM is attached to a system via a serial bus on a platform that
suffers bit flips, we can get back dangerously wrong data. This patch
series aims never to do a direct copy into a kernel buffer based on an
unchecked size value returned from the TPM.
